In Germany February 6, 1931 20 Claims; (Cl. 131-39) Methods-have alreadybeen proposed for deliveringthe cut tobacco to the tobacco spreaders ofcigarette-making machines by. pneumatic means. Although it is possiblein this manner to replenish the amount of tobacco which is being used,it does not solve the problem of distributing this quantity of tobaccoduring its passa'geffrom the separator into the spreader, in such mannerthat it forms an extremely even layer which exe tends over the entiretobacco spreader as far as the walls. This is, however, necessary inorder to obtain a uniform performance of the spreader.

According to this invention an impact surface is placed in the path ofthe deliveryair, which impact surface corresponds to the length of thespreader rollers. l I

These surfaces are preferably reciprocated transversely to thelongitudinal direction of the rollers varying the tobacco receivingspace of the spreader. The surface may, however, be curved in such a waythat the tobacco particles which arrive thereon are flung off downwardsat an angle of dispersion, and this angle can be so adjusted that itcovers the entire surface in question of the tobacco spreader. I y

In order to bring about a uniform distributio of the tobacco on theimpact surface it is advisable to fit in front of the surface awedgeshaped distributor against which the stream of tobacco impinges.This distributor can be adjusted in such manner that its apex is alwaysdirected towards the middle of the on-coming stream of tobacco. l

To enable the invention to be fully understood it will now be describedwith reference to the accompanying drawing, wherein:

Fig. 1 is a vertical longitudinal section.

Fig. 2 is a plan. I

Figs. 3 and 4 are detailed views.

The current of air carrying thetobacco is conducted into the separator 2by means of the pipe 1. Between the pipe 1 and the separator '2 there isinserted a funnel-shaped member 3, the wide end of which is directedtowards the separator 2.

' In the separator 2 there is arranged a metal plate 4 which extendsover the entire width of the separator. To the metal plate 4, thehorizontal part 4 of which overlaps the upper end 3 of the wide end ofthefunnel-shaped member, there are attached two pins 5 which are passedinto slots 6 of the upper wall 6 of the separator. The upper end of thepins 5 serve as pivots for the connecting rods 7, the otherends of whichare pivotally attached to the crank pins 8 of discs 9. The discs 9 aremounted onashaft 10 which is mounted in a bearing 11. The latter isattached to a projection 12 of the distributor. On the shaft 10 there isalso mounted a sprocket wheel 13 which is driven by a chain 14. On themetal plate 4 there is also attached a distributor 15 of triangularcross section, the deflecting sides of which are concave as shown inFigs. 1, 3 and 4. Figs. 3 and 4 are, respectively, sections on the lines33 or 44 of Fig. 1.

The on-coming tobacco first of all impinges on the distributor l5 and isthereby distributed over the entire plate.

From the plate 4 a part of the tobacco flows downwards, and a part isscattered in the manner indicated in Fig. 1, so that it is uniformlydistributed. Now, by the rotation of theshaft 10 the plate 4 is movedcontinually to and fro between the position indicated by full lines andthat in dicated byv dotted lines, so that the tobacco is cli tributedover the entire surface at of the tobacco spreader "16. V

In order that the distribution of the tobacco may be asuniform aspossible, it is absolutely necessary that the distributor member 15should be exactly in the middle of the oncoming stream of tobacco. Asshown for instance in Fig. 2, the pipe 1 may, however, be curved beforeit discharges into the distributor 2. In this casethe stream of tobaccowould not be directed towards the middle of the tobacco distributor ifthe latter were exactly in the middle of the separator. vNow in order.in such cases to make it possible for the distributor member 15 to belocated exactly in the middle of the oncoming stream of tobacco it isarranged adjustably on the plate 4. For this purpose the plate 4 isprovided with a transverse slot 1'? through which the adjusting screw 18of the distributor member 15 protrudes. Now, by adjusting thedistributor member so that it comes into position in the middle of thestream of tobacco, it is easily possible to procure a uniformdistribution of the tobacco over the surface a: of the tobacco.spreader, even if, owing to, bends in the pipes or the like, the streamof tobacco arrives obliquely in the separator.
